Macro for automatic numbering

Hello all,

I hope that you can help me with a problem. Since a few days I switched from my Windows PC to a Mac. Everything is working now except for one macro, I used the following macro on Windows but can't get it to work on the Mac:

Creating sequentially numbered documents (such as invoices) (wordmvp.com)

What I understand already is, that I had to change the file path. That I tried already, but the Macro is still always setting the number to "001".

Do you have any idea what I have to do?

Thanks and best regards,
